Abstract

A cowl includes a bottom cowl, a top cowl, and a clamp device. The bottom cowl opens upward. The top cowl opens downward and closes an opening of the bottom cowl. The clamp device detachably couples the top cowl to the bottom cowl. The clamp device includes a clamp and an operating lever that operates the clamp. The clamp is disposed inside the cowl. The operating lever is disposed outside the cowl. A mating portion between the bottom cowl and the top cowl includes a first mating section and a second mating section as seen in a side view of the cowl. The first mating section extends rearward from a front end portion of the cowl. The second mating section extends upward and rearward from a rear end of the first mating section. The operating lever is located above an extension line defined by extending the first mating section rearward as seen in the side view of the cowl.
